  • DES-EDE3-CBC is unsupported after enabling FIPS

    Posted on

    Hello,

    After enabling FIPS on RHEL 9, the DES-EDE3-CBC cypher becomes unsupported:

    $ openssl enc -des-ede3-cbc -base64 -K 17839778773fadde0066e4578710928988398877bb123789 -iv 0000000000000000 /dev/null
    Error setting cipher DES-EDE3-CBC
    808B1AD24E7F0000:error:0308010C:digital envelope routines:inner_evp_generic_fetch:unsupported:crypto/evp/evp_fetch.c:349:Global default library context, Algorithm (DES-EDE3-CBC : 27), Properties ()

    Is the use of this cypher not allowed under FIPS?

    For contrast I tried the same on Ubuntu and it is supported there.

    Thank you!
